PAPER CLIP.

Application filed March 21, 1923. Serial No. 626,511.

T 0 all whom it 11264;, concern.

Be it known that we, MAXIMILIAN J. HUBENY and HERMAN A. FRAHM, both citisens of the United States and residents of Chicago, in the county ofCook and State of Illinois, have invented a new and useful Improvementin Paper Clips, of which the following is a full. clear and exactdescription.

Our invention relates to improvement in paper clips and consists in theconstructions, combinations and arrangements of parts herein describedand claimed.

An object of our invention is to provide a paper clip of the characterdescribed in which the cooperating gripping members are rendered moreeffective in a novel and simple manner.

A further object of our invention is to provide a paper clip of thecharacter clescribed which will not slip longitudinally when placed inposition as in binding together two or more pieces of paper or the like,and ultimately slip from engagement with the paper or other objectsbound together thereby. The ordinary type of paper clip which does notpierce the paper has been found to possess the disadvantage of movingrelative to the paper and slipping therefrom.

A further object of our invention is to provide a paper clip of thecharacter described which actually interlocks the adjacent plies ofpaper held together thereby without mutilation to the paper.

A further object of our invention is to provide a paper clip of thecharacter described which is simple in construction, durable and whichis thoroughly practical for the purpose intended.

Other objects and advantages will appear in the following specification,and the novel features will be particularly pointed out in the appendedclaims.

Our invention is illustrated in the accompanying drawings, foring a partof this application, in which Figure 1 is a front elevation of anembodiment of our invention,

Figure 2 is a side elevation of the "device illustrated in Figure 1,

Figure 3 is a side elevation of the device shown in Figure l operativelyapplied,

Figure 41- is a front elevation of a modified use of a paper clipcomprising a metal wire 1 bent laterally 1n the manner shown 1n 21g. 1.so that two cooperating portlons or w loops 2 and 3 are provided. Theloop 2 is disposed within the loop 3 and is shorter than the loop 3.These loops we choose to term the cooperating gripping members of thepaper clip.

So far the structure is identical to the structure of paper clips wellknown in the art.

The wire of which the clips are constructed is of a substantiallyresilient quality so that the clips tend to hold their shape afterlimited distortion.

Our improved paper clip differs from the ordinary type of paper cliphowever in that the intermediate portion of the clip, i. e. that portionbetween the upper end 4 and the lower end 5 is provided with a pluralityof uniform convolutions all in the same plane and transverse to theplane of the loops or gripping portions 2 and 3. These convolutions areindicated at 6 in the drawings. See Fig. 2.

The convoluted portion of the clip is not only uniform in the separateconvolutions thereof but is also uniform as to the four portions of thewire 1 which lie in the same plane and serve to form parts of the loops2 and 3. This uniformity of the four portions of the wire 1 is perhaps.most clearly illustrated in Fig. 2.

In Fig. 2 it will be noted that only the convolutions in the adjacentportion of the loop 3 may be seen. This is because the convolutions ofthe other three portions of the wire 1 comprising the remainder of theloop 3 and the loop 2 are exactly in line with the adjacent portion ofthe loop 3 as seen in Fig. 2.

From the foregoing description of the various parts of the device, theoperation thereof should be readily understood. In Fig. 3 we have shownone of our improved paper clips applied to two superimposed pieces ofpaper. It will be noted that the paper has assumed the same shapebetween the adjacent and cooperating loops or grip ping portions 2 and8, that the clip itself possesses.

The adjacent pieces of paper have therefore actually interlocked withone another and it would take a pull suflicient to fie}; the paperthrough the convoluted path in which it is disposed to separate thepieces of paper.

There is very small possibility that the paper clip Will becomedislodged from the paper unintentionally since the movement of the clipfrom the paper must also cause the paper to flex.

In Fig. 4 we have shown a modified torm of our invention, in which formwe reverse the plane in which the convolutions of the intermediateportion of the clip, disposed.

The clip shown in Fig 5 therefore is the one illustrated in Fig. 4;viewed from the side.

The operation of this modified form of our invention is precisely thesame as the ordinary type of paper clip. The results accomplishedhowever are somewhat different. This. form of our invention provides anenlargement of the paper contacting surface of the paper clip andtherefore a more secure grip of the clip on the paper. The ordinary typeof paper clip may be drawn off of the paper by moving the cliplongitudinally away from the paper. In our present invention, both inthe preferred form and the modified form illustrated in Figs. 4, 5 and6, the clip is constructed in such a manner as to resist the movementtending to remove the clip from the paper to which it is attached orengaged with.

e claim: I

1. A paper clip of the character described comprising apair of loopmembers forming an integral part of said clip, said loo-p members beingdisposed one within the other and substantially in one plane, theintermediate portion of said clip including in part said loop members,being convoluted in a plane transverse to the plane of said clip.

2. A paper clip of the character described comprising a pair ofcooperating gripping members arranged to receive sheets of paper or thelike therebetween, said gripping members having convolutions in theirWork engaging surtaces transverse to the plane of the work engagingsurfaces.
